It was expected but that should be introduced early in the story with other problem as the reason why they have a hard time to fight together, not introduced 5 season later. I feel like the author didn't know how to handle or progress the story properly. There is no proper plan or structure at all. Atp, it's just a waste of time, don't you think so? They could just write another story and put that problem and make it worse in that story

Ik imma get flamed for this but I do like that there are bigger stakes at play rn...like till now their love life was pretty chill which i absolutely loved but tbh considering Taesung comes from a rich family, its almost like there were no issues with anyone from his family knowing their son/grandson is gay. Altho i do feel terrible for both them rn. I hope they end up together n put that grandfather six feet under >:3
